  • Stimulator system
    Patent number: 4431001
    Abstract: An electrical stimulator system is described incorporating rechargeable batteries and a charging circuit. A charging set and electrode support are alternatively connected to the stimulator system via a single common two-pole terminal. The system is designed to prevent current from flowing directly from the battery to the electrode support along the charging circuit while allowing charge current to flow in the opposite direction along the charging circuit if the charging set is connected to the system instead of the electrode support.
